Hitting The Track: Nitro MP9 RTR to 1/8 Race Buggy - Part 2 

It helps that it's a decent engine as well. So many people get one of the Traxxas TRX 3.3 equipped models or a something with a super cheap low-quality engine, have trouble with it, and then end up thinking that all nitro models are like that. I've never had issues with any of my Dynamite Platinum series (SH Engines) engines, but I've had plenty of trouble with Traxxas engines and the piece of crap that came in the old Kyosho Inferno US Sports Readyset back from the mid 2000s.

@@VestedUTuber agreed i have a revo 3.3 after i changed the motor to an OS I was so shocked

Yes, I agree! -Brett

HA! That would be fun. Just box stock cars only. Would you allow different tires? -Brett

@@AMain_Hobbies yeah, its more fun to drive with better tires. But I would like to regulate it so people with most tires in the backpack don't automatically win. Perhaps not go for the softest ones around, but allow for something that is still better than what comes with an RTR car, yet can stand up for a couple of days racing. I would also allow for oil changes in diffs and shocks, also changing springs and such.

That's a great way to get your feet wet in the 1/8 nitro scene Robert. What kits are you looking at? -Brett

@@AMain_Hobbies Looking at Mugen and Kyosho,. By upgrading my MP9 RTR I've bought time to continue learning/experimenting with chassis set-ups, tires, differential and shock fluid viscosity's etc. and I've started to go racing with it too. A-Main Manufactures Cup @ Chico this year was my 1st. Got my Butt kicked as expected but Wow What FUN! My upgraded MP9 RTR was track capable even in the hands of a Rookie. Getting rid of the pull start was "key", it probably added 10% HP but most notably "unleashed" top end RPMs'. Thank you for doing and sharing these videos.

You raced at our track!!! Your a local then, or somewhat local. Glad you could come out and get a race in on your buggy. Really happy to hear you getting track time on your RTR and taking your time to gain the experience and knowledge. It's a good path. Let me know if you ever need anything. -Brett

Wow, congratulations Erik! Happy you enjoy the videos too! -Brett

It works great! -Brett

Hmm, the wheel should not need adjustment. If it does, it may not have been assembled correctly at the factory, or there is an alignment issue with the vehicle. Happy you fixed it though and got it working properly. -Brett

Bert, it took me a while and thanks to other Kyosho MP9 Owners for the suggestions. My first time was not good on the track LOL. Damn near passed out because of heat and lack of preparation. Can’t want to get back out there. I don’t know how you guys do in the triple digits. Peace be with you.

@@TrashMan2008 Excellent. Glad you got out there and gave it a go! Driving nitro in heat is definitely a good way to feel scorched. Hopefully many more cooler days at the track ahead! -Brett

Word

I'll Braaap to that! -Brett

I just wish I didn't live with neighbors all around and a thin parking lot with pure cars parked. So I will either go 3d helicopter lol or inferno mp10E just came out.

Very wrong

@@lennartkrischik4757 What are you ten years old? lol

Sad nitros are so fun but not many people in the hobby are into them much anymore

Absolutely! -Brett

AMain Hobbies thank you! Will be picking one of these up

The servo circuitry was not made and designed to cope with the high voltage, so after a while, it burns up. The servo will work on 7.4V, but will fail prematurely, compared to using the servo on 6V. A high voltage servo is made with a more robust circuit board and motor to handle the additional voltage, and heat that comes along with it. -Brett

That could be a good option for some. But most new folks don't have an extra connector and wire. We just figured if you go with a single 4S right from the start, there is no need for anything else. But a jumper is a good option. -Brett

AMain owns and operates two tracks Jayson. C'mon! ---> tracks.amainhobbies.com/silver-dollar-rc-raceway/ -Brett

Until recently, the backplate has been available to AMain Hobbies. But, we have some on the way now. Here is the preliminary product page if you want to bookmark it: www.amainhobbies.com/kyosho-back-plate-set-kyo74019-09/p1002074?r=0 -Brett

Yeah, come race with us! It's called the Silver Dollar R/C Raceway. It's the AMain Hobbies track. Heres the track site: tracks.amainhobbies.com/silver-dollar-rc-raceway/ -Brett

This ReadySet is an awesome RTR buggy. There are tons of parts available as well to go to extreme basher, or competitive racer. It's up to you. But it Braaaps hard. Hope you're all recovered and back on the board dude! -Brett

This is a great little charger (i like the touch controls too): www.amainhobbies.com/protek-rc-prodigy-680-touch-ac-lipo-life-ac-dc-battery-charger-6s-8a-80w-ptk-8513/p260579 To charge the receiver pack, this lead is the way to go: www.amainhobbies.com/protek-rc-receiver-balance-charge-lead-2s-to-4mm-banana-w-4s-adapter-ptk-5319/p244687 Hope that helps. Let me know if you have any other questions. -Brett

@@AMain_Hobbies great, thank you for your reply, im trying to gather everything, and a car to the cart, what kind of nitro gas do you recomend for the mp9 tki4 RTR buggy

Performance is pretty peppy, but fuel mileage is not very good. You could use it for fun racing, but I wouldn't try to be a serious racer because of the low fuel economy. -Brett

AMain Hobbies what would you recommend as an alternative buggy to this for racing with better fuel economy? Thanks in advance

No other buggy is needed. You can just swap out the engine for something more race oriented. A ProTek Samurai, an OS Engines, even a SH Engine will all provide increased mileage. There are a lot of engine options for a variety of budgets and competition levels. -Brett

We weren't able to find one. We heard others have found one that worked but there doesn't appear to be one from Kyosho. -Brett

No, it was probably an error on my part. -Brett

@@AMain_Hobbies Actually, you were right! I ordered and received the SureStart about 3 weeks ago, and the motors are actually 775's. AMain's product page should to be updated.

​@@charlesbonkley Wow, really? Thanks for letting me know; I'll look into that. -Brett

Yeah probably was. AMain Hobbies has a few running for special projects. -Brett

Yes sir. It shouldn't cause any issues as long as the one-way bearing in the pull-start holds up. We may not even put the back plate on our engine if it holds up. We'll see. -Brett

AMain Hobbies last question did the stock engine mounts allow you to get the flywheel at the right height for the starter wheel to catch? Thanks!

I was wrong. It was the backplate for the pull-starter assembly, not a full replacement. Sorry. -Brett

@@AMain_Hobbies there won't be any part coming from a third-party manufacturer either right?

I don't think so. That engine has been around for years so an aftermarket backplate would have been an option by now. -Brett

From memory, I believe it is 25% nitro. -Brett

Oh ok, thank you...

@@AMain_Hobbies BTW, was it the Pro Race or Tessmann?

@@aei711 I think it was this Nitro Race: www.amainhobbies.com/powermaster-nitro-race-25-car-fuel-9-castor-synthetic-blend-one-quart-pow6137/p233418

No. The backplate we purchased was incorrect and did not work. Kyosho doesn't sell a backplate cover as far as we know. People have commented on these videos about a Duratrax or Dynamite plate intended for a different engine, that fits. I do not know the model number though. We left the pull start on there and it's still on there today. Good luck finding one. -Brett

For bashing around and having fun they're both great. But if you want to go on the race track and have the best performance, the MP9 will be better suited. -Brett

@@AMain_Hobbies oks nice friend , thanks

Yeah, a good amount of what we do is electric. How about you; do you mainly drive nitro or electric? -Brett

AMain Hobbies I’m a nitro 1/8 guy through and through but Mugens for me 🤘🏻🤘🏻

It's the Silverdollar R/C Raceway in Chico, Ca. Here is the track site if you want to check it out: tracks.amainhobbies.com/silver-dollar-rc-raceway/ -Brett

Hi Edward. We are experiencing a high order volume right now so orders are shipping about two days after they have been placed. Hope that helps. -Brett

Thank ..

I just bought one thank for the info cant wait until get here..?

@@edwardacosta6142 Congratulations Edward! That's great news. The buggy should ship out shortly. Sorry for the wait right now. It is not normally like this. I hope you get your new buggy soon! -Brett

Thank suck that rc track close

HA! The nitro fumes tame out the goof. -Brett

I love the smell of nitro/castor oil in the morning and yes i remember when we used castor oil, methanol and nitro to mix our own.

I concur, but I would like to add brappp can be for any 2 smoke machine including dirt bikes. but yes a 701 superjet with factory pipe is brapp!

@@patandbrandi lol👍👍

@@patandbrandi lol👍👍

I have brought shame to my family. Apologies. -Brett

Spread your hate speech somewhere else. #NITROGANG -Brett

@@AMain_Hobbies Hey I hope it doesn't but lets be real they nitro cars you can get are Chinese junk you can't get parts for or ridiculously expensive racing kits that are out most peoples budgets.

I have both electric and nitro. The electric has alot of power but it also has no personality. I drive the nitro much more.

Nitro all the way for me!

Because it's easier to start the engine that way. It doesn't matter if there is a pull start or not, you can still use a starter box on this platform. Why not make it easier on ourselves? -Brett

@@AMain_Hobbies I would have picked up an used race engine instead. Maybe it needs a new conrod but it will smoke that rtr engine

Plus! Drop the factory bitch pinion gear and drop in a 17 tooth pinion and watch how that kyosho opens up!

Because he does hit the track???

You can't lower the engine? The flywheel needs to be able to touch the rubber wheel. -Brett
